‘Ubaidullah bin Abi Yazid narrates that he heard from Sayyiduna Ibn Abbas (may Allah be pleased with them). He was asked about fasting on the day of ‘Ashura, so he said: I do not know that the Messenger of Allah (peace and blessings be upon him) fasted on any day, seeking the virtue of that day over other days, except this day, and of any month except the month of Ramadan (that is, among the days, he considered the day of ‘Ashura virtuous, and among the months, Ramadan).
